I am having difficulty walking. This only happens after being on my feet doing usual activities for a few hours. My feet become so painful that I have to rest them, then when I get up to simply walk across the room, I am almost hobbled, often holding onto furniture as I move. I am only 53 and feel like I'm 30 years older. I know losing weight would help but find it difficult to exercise like I used to. My joints don't hurt much, it is more on the bottom of my feet. My calves become very tight as well.
